Inferences and recall at ages four and seven.

Inferences and recall at ages 4 and 7 were studied as a function of the cause of a target event, the presence and timing of questions prior to recall, and the type of inference demanded by the questions. 7-year-olds inferred and recalled well with stories containing any of the causal connections employed in the study. 4-year-olds performed better when physical causes, rather than either psychological causes or enabling relations, connected events. Timing of questions did not affect the 7-year-olds' inferences, but asking questions interfered with their recall. Questions about story events aided the 4-year-olds' ability to make inferences and to recall, especially when causal connections were least specified and when questions were asked following the story. 4- and 7-year-olds also differed in responding to demands for 3 specific types of inference. 4-year-olds produced significantly more unconstrained inferences than logical or constrained informational inferences. 7-year-olds were most responsive to logical inference questions, and produced significantly more logical than constrained inferences.
